Used in compound modules

Name	Type	Description
EtherHost	compound module	An example host with one Ethernet port and a traffic generator that generates request-reply traffic directly over Ethernet. This host model does not contain higher layer protocols (IP, TCP). By default it is configured to use half-duplex MAC (CSMA/CD).
EtherHost2	compound module	An example host with one Ethernet interface and an Ethernet traffic generator directly connected to it. This host model does not contain higher layer protocols (IP, TCP). By default is configured to use half-duplex MAC (CSMA/CD).
EthernetInterface	compound module	Ethernet network interface. Complements EtherMAC and EtherEncap with an output queue for QoS and RED support.

Parameters

Name	Type	Default value	Description
dataQueueType	string	"DropTailQueue"	class that inherits from IOutputQueue (DropTailQueue, EtherQoSQueue, DiffservQueue etc.)

Properties

Name	Value	Description
display	i=block/queue

Gates

Name	Direction	Size	Description
in	input
out	output

Unassigned submodule parameters

Name	Type	Default value	Description
pauseQueue.frameCapacity	int	100
